FIELD: veterinary medicine.
SUBSTANCE: method comprises individual testing on blood groups of both parents. Selection is then carried out taking into account the extent of their genetic differences, expressed in terms of antigenic similarity index ranging from 0 to 1. At that the morphologic condition of placenta is additionally determined, and the selection of parent pairs is carried out with the genetic compatibility of average index values of antigenic similarity in the range of Ra=0.31-0.60 and with the morphostructural condition of placenta weighting 310-330 g, the number of cotyledons of 68.4-76.2 pcs., the distance between the cotyledons of 2.2/2.5-2.7/3.0 cm.
EFFECT: method enables to increase the birth rate of viable and highly productive offspring.
